Be it known that I Join A. LAMon'r, a citizen of the United States, andresident of Granite City, in the county oi Madison and State ofIllinois, have invented certain new and useful Improvements in Spring-Plenk-Locking Devices, of which the fol-- lowing is e, specification.

My invention relates to car trucks and articular reference to a novelspring plank locking device for use in connection therewith.

It is essential in the operation of car trucks that the side framesshall be tied together intermediate their ends this usually bitingaaiomplished by the use of a spring nk or similar connecting device. Inthe use of east side frames it. is desirable that means shall beprovided for readily disentying member therefrom and devices have beenproposed with that However, all of these devices have certain objectionswhich are sought to many be overcome in the present structure.

plank may or may not be provided with the flanges 14. At each end theplank 12L is provided with font apertures 15, re ax-tering with similarapertures 1&3, through the seat 19. As a locking means I provide a block1'7, having bosses 18 projecting from one face thereof, these bossesbeing adapted to enter the registering openings in the spring plank andseat. On the upper surface of the block 17, are small recesses 19, withwhich lugs, carried by the spring reminer, may coiiperate.

It will be seen that by the use of the construction shown the springplank is securely held in place without the of rivets or bolts and thata comparatively light spring lank may be employed, the lockinq memherfor the parts providing also a block on which the springs may rest.

The construction is capable of considerable modification and suchmodifications as are within the scope of my claims I consider within thespirit of my invention.

I claim:

1. In a car truck, a side frame having an apcrtured seat. a spring plankand a block il'fivldfid with bosses, said block resting upon said plankand said bosses serving to lock said spring plank and side frametogether.

2-. In a car truck, the combination of a side frame having an aperturedseat, a spring plank having apertures registering with those .in saidseat, and a block having bosses registering with the apertures in saiplank and seat and adapted to removnbly loci; the parts together.

3. In a car truck, the combination of a side frame member having anepertured seat, a plate extending between adjacent side frames, saidplate being provided with apertures in its ends registering with thezipertures in said side frame tnemberm springsupporting block, and lugson said block, said lugs being adapted to enter apertures in said plateand side frame member an lock said parts together.
